The present invention aims at providing a cover structure of a tactile sensor and a tactile sensor that can secure sufficient adhesion between a sensor body and a covering layer without providing an adhesive layer and have no possibility of causing a sensor to make detection error due to the covering layer formed thereon. A cover structure of a tactile sensor according to the present invention includes a sensor bodyand a covering layermade of elastic body molded on the sensor body. The covering layerincludes at least two layers of an outer layerdisposed as the outermost layer and an inner layerdisposed to come in contact with the sensor bodyand having a higher adhesiveness and a lower hardness than those of the outer layer, and is integrally molded with the sensor bodyby the cast molding. It is preferable that the sensor bodybe disposed on the top surface of the base, the covering layercover over the sensor bodyand the base, and the inner layerdo not cover the bottom surface of the base

An object is to provide a covering material and a covering structure of a robot gripping portion capable of providing proper gripping performance depending on various objects to be gripped so as to grip the objects and is solved by a covering material disposed on a surface of a base materialhaving a function of gripping an object, including an inner layermade up of an elastic body and an outer layermade up of an elastic body coming into contact with the object when gripping the object on a surface of the inner layer, the inner layerbeing made up of the elastic body having a tackiness and having a hardness lower than the outer layer, the outer layerhaving one or more penetrating portionspenetrating to the inner layersuch that when a stress acts at the time of gripping of the object, a portion of the inner layerenters the penetrating portionor protrudes from the penetrating portiondepending on a magnitude of the stress.
